LUMATEPERONE vs REXULTI
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lumateperone is an atypical antipsychotic with a unique mechanism of action: it acts as a 5-HT2A receptor antagonist, a dopamine D2 receptor antagonist, and a serotonin reuptake inhibitor. It also modulates glutamate via enhanced AMPA and NMDA receptor activity.
Partial agonist at D2 and 5-HT1A receptors; antagonist at 5-HT2A and α1B/α2C adrenergic receptors.
42 mg orally once daily, taken with food and at least 240 mL of water, with a titration schedule: 42 mg daily for 7 days, then 21 mg twice daily thereafter.
2 mg orally once daily initially; increase to 4 mg once daily no sooner than week 2; target dose 4 mg once daily; range 2-4 mg once daily.

Terminal elimination half-life is approximately 13 hours in the plasma, supporting once-daily dosing. Steady state is reached within 5–7 days.
Terminal elimination half-life is approximately 19–23 days for brexpiprazole and its major metabolite DM-3411, requiring up to 2–3 months to reach steady state.
Approximately 80% of the dose is excreted in feces (as unchanged drug and metabolites) and about 11% in urine. Less than 1% is excreted as unchanged lumateperone in urine.
Approximately 25% of the dose is excreted in urine as unchanged drug and metabolites; about 54% is excreted in feces. Renal excretion of unchanged drug is minor (<1%).
